SMOKING-PIPE.

SPECIFICATION forming part of Letters Patent No. 665,187, dated January 1, 1901.

Application filed July 21, 1900. fierial No. 24,402. (No model.)

To 00 whom it may concern.-

Be it known that I, WALTER O. CUNNING- HAM, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Smoking-Pipes, of which the following is a specification.

This invention relates to smoking-pipes in which the bowl and its stem are divided lengthwise of the pipe into two sections which are detachably interlocked, so that upon separating the sections the interior of the bowl and the smoke-passage are exposed and can be convenientlyand thoroughly cleansed. A pipe of this kind is shown and described in Letters Patent of the United States No. 628,395, granted to me July 4, 1899.

The object of my present invention is to im prove the construction of the devices whereby the sections of the divided pipe are inter locked, with a view of increasing the strength of the lock, reducing its cost, and permitting the sections to be quickly and conveniently interlocked and disconnected.

In the accompanying drawings, Figures 1 and 2 are interior side elevations of the pipesections. Fig. 3 is a longitudinal section of the pipe, taken through the joint thereof. Fig. 4 is a transverse vertical section taken centrally through the bowl in line 4 4, Fig. 3. Fig. 5 is a sectional top plan view of the pipe, the plane of the sectional portion beingin line 5 5, Fig. 3. Fig. 6 is a horizontal section in line 6 6, Fig. 3.

Like letters of reference refer to like parts in the several figures.

A and B are the members or sections of the divided pipe-bowl, which meet in a vertical joint extending lengthwise of the pipe. One

of the bowl-sections-say the section Aisprovided on its inner fiat facewith a laterally-projecting stud or tenon c, of cylindrical form, having at its outer end one or more radial lugs a, while the other bowl-section B is provided in its opposing flat face with a circular undercut cavity or socket d, which is adapted to receive the stud c. The socket d is provided in its contracted outer edge with notches or recesses d for admitting the lugs c of the opposing bowl-section into the enlarged or undercut portion of the socket. In the construction shown in the drawings the stud c has three equidistant lugs c andthe socket d is provided with a corresponding number of notches d.

In interlocking the sections of the bowl the same are brought together with the lugs c of the section A in line with the notches d of the other section, in which position the stud c is free to enter the socket d and the opposing flat faces of the sections are allowed to bear against each other. After inserting the stud in its socket the bowl-sections are turned on each other in opposite directions sufficiently to move the, lugs of the stud out of register with the notches of the socket, thereby interlocking the logs with the unnotched edge of the socket, as shown by dotted lines in Fig. 3, and uniting the sections of the bowl. The lugs 0 and notches d are so arranged that they register only when the bow1- sections are out of line with each other, so that upon turning the bowl-sections into their normal position the lugs are interlocked with the edge of the socket d. The inner faces of the lugs c are preferably beveled and arranged obliquely, and the undercut edge of the socket d is provided with corresponding faces, as shown in Fig. .6, so that in turning the bowl-sections from their abnormal to their normal position for interlocking the same the contiguous oblique faces of the socket and the lugs firmly draw the bowl-sections together, thereby insuringa tight joint. The interlocked bowl-sections are held against displacement by the ferrule e of the mouthpiece E, which embraces the sections f of the divided'stem, as shown in Fig. 3. To separate the bowl-sections, the mouthpiece is simply removed and the bowl-sections are turned oneach other sufficiently to bring the lugs 0 into register with the notches d of the undercut socket, when the sections can be disconnected. This improved locking device is comparatively strong and inexpensive, and as it requires but a partial turn of the bowlsections to lock or unlock the same the sections can be readily separated and connected.

g is the smoke-passage, leading from the bowl to the end of its stem. This passage sections, asshown in Fig. 2.

expensive construction than one in which the smoke-passage is formed partly i 11 one section and partly in the other.

I claim as my invention---- 7 A smoking-pipe having its bowl and stem divided vertically and lengthwise into two sections, one of said sections being provided on its inner side, below the howl-cavity and at a distance from the outer surface of the bowl, with a cylindrical stud which is pro vided with a laterally-projecting lug, and the other section having a corresponding: n'ndercut socket provided in its edge with a notch which is arranged to register with the lug of said stud when the sections of the bowl are turned out of line with each other, substantially as set forth.

'Witness my hand this 16th day ofJuly, 1900.
